SPECIPICATIJQN forming part of Letters Patent N... 381,186, dated Apri117,'1 8 88.'

' Application filed September 14,1885. Serial No. 117,090. (No model.)

To all whom it may concern:

' .Be it known that we, REINHARD, T. ToR- KELSON and "IVER JOHNSON, bothof the city and county of Worcesten'and Commonwealth and usefulImprovements in Planes; and we do'hereby declare that the following'isafnll, clear, and exact descriptionof the same, reference being had tothe accompanying drawings, forming a part of thisispecificat'ion, in,which I Figure 1 represents a verticalsection through the ends of theplane on line b 0,.Figs. 2 and 3; Fig. 2, a top or'plan view of thefront of the I 5 plane; Fig. -3, a top or plan view'of the rear sectionof the plane with the handle removed;

Fig. 4, a side View of thehandleand a small section of the plane-bed;and Fig. 5 represents a cross-section on line a, Fig. 1', looking in thedirection of arrow 1. v

To enable those skilled in the art to which our invention belongs 'tomake and use the same, we will proceed' to describe it more in,

detail, the nature of which consists, first, in

certain improvements in the construction of an adjustable throat device;second, in improvements in the construction, whereby the handle maybedetachably fastened to the bed;

and, third, in animptoved plane-bed, all as.

will be hereinafter more fully described.

I In the drawings, A represents the bed of the plane,which is providedwith corrugations d, the lower edges, e, of whichare flat, and' upon itsupper side with round corrugations 3,5 f. By this construction of thebed it can be made dovetailing to fit, and, consequently,

while the nut can bemoved back and forth' it.

cannot be raisedoutof place until screw 0 andthroat B are removed. V

The body, part E of the adjustable throat rests upon upright flanges 9,(shown in full of Massachusetts, have invented certain newlines, Fig..1, andjdotted lines, Fi .2}; and" 1 between the side flanges of theplanebed F F. v A forward projection, G, fits 'into the throat .f 1H,and which projection can be slid back and 5 forth,as indicated in fulland dottedline's, Fig. 1, and-quickly adjusted, by means of thethumb-screw O, to give; any desired opening to the th rjoat H. Thisarrangement also leaves the under side of the bed of the plane smooth,6o

thereby obviating the objections to the adjustable throatsheretoforefitted to work on Q 4 of vulcanized india-rubber. It is madehollow, 6 g

as seen at I, andwitha rounded base, J," to fit intoa socket-piece,K,;,whic h in turn ismade with an oblong slot, t, having edg'esinclinedtoward each other, so that said socket-piece K [may be placed over thedovetail projection L on bed A,aud when forced forward into theposi-'tion shown in Fig. 1 it is securely held in said I position verticallyunder the beveled edges k of said projection L. The bas'eof handle I isnow placed in the socket-piece K, and;the .75 screwrod M passed downthrough thetop and screwed into hole M in the dovetail'projection L,thereby securing the handlefirmly in po-' sition,while at the same timeadmittingof the detachment of said handle in an easy and ex 801 Ipeditious manner. Aforward'projection, N, I is cast upon the under sideof the top of. the handle, as fully indicated in Fig. 1, and a metalsocket-piece, Z, is fitted into the top of handle rod M. I The sides ofthe handle'are made with a seriesof notches or corrugations, 0, wherebyI when the handleisclasp'ed inthe hand the t q soft skin and flesh ofthefingers will be pressed 1 f I into the corrugationsandnotches on oneside 0 V of theihandle, while the skin and soft fleshof the hand at thebase of the fingers will be presspd into the corrugations upon the OPPsite side of the handle. I By this-arrangement I theloperator can handlethe plane much easier 5 I1 and with less eirertion, particularly when heis obliged to hold up the plane to plane the edge of a piece of board,which is frequently, required in the usual work'of a carpenter. flf

the handlewere smooth, a little perspiration: too. I

or oil would require'a great strain uponthe I fingers and cords of thehand to hold the plane I j from turning; but with the corrugations asmade upon the sides of said handle the difficulty is obviated. Ifpreferred, the socketpiece K may be cast with the bed of the plane anddovetail projections omitted.

\Ve are aware that planes with adjustable throats have been used before,and we do not therefore claim said device, broadly.

Having described our improvements in planes, what we claim therein asnew, and desire to secure by Letters Patent, is-

1. The combination of bed A, having the rear projection, L, upon the topthereof provided with the dovetail or bevel edges k, substantially asdescribed, with the detachable socket-piece K, provided with an oblongvertical slot, t, having edges inclined toward each other, and adaptedto be placed over said projection L, then forced forward and held ver-20 tically under the beveled edges is aforesaid,

handle I, fitted at the bottom in said socketpiece K, and fastening-rodM, passed longitudinal] y through said handle and into bed A,substantially as and for the purpose set forth.

2. In a bench-plane, a throat-adjusting device located above the bed Ain front of the throat H, consisting of said bed having the dovetailflanges F F and supporting-flanges g, in combination with the slide B,arranged over said flanges, and having the projection G next to saidthroat, the nut D, fitted to slide longitudinally over thebed betweenthe dovetail flanges F F aforesaid, the latter holding said nut andslide B in position vertically, and thumb-screw O, fitted to turn insuitable vertical openingsv in the slide and nut, substantially as andfor the purpose set forth.
